Abstract

Beschrieben sind eine Drehwinkelsensoranordnung und ein Verfahren zur Feststellung der Drehposition α einer Welle 12. An der Welle 12 ist eine Scheibenanordnung 1 mit mindestens einer Scheibe 16a, 16b, 116 angeordnet, die mindestens am Umfang aus ferromagnetischen Material besteht. Die Scheibenanordnung 1 weist eine am Umfang über die Umdrehung der Welle 12 variierende radiale und/oder axiale Anordnung des ferromagnetischen Materials auf. Ein Magnetelement erzeugt ein Magnetfeld, dessen Feldverteilung durch die Scheibenanordnung beeinflusst wird. In einer gegenüber dem Umfang der Scheibenanordnung 1 angeordneten Magnetfeld-Sensoreinheit ist ein Magnetfeld-Sensorelement 22 vorhanden, das die Richtung des Magnetfeldes feststellt.

Described are a rotation angle sensor arrangement and a method for determining the rotational position α of a shaft 12. On the shaft 12, a disc assembly 1 with at least one disc 16a, 16b, 116 is arranged, which consists at least at the periphery of ferromagnetic material. The disk assembly 1 has a circumferentially over the rotation of the shaft 12 varying radial and / or axial arrangement of the ferromagnetic material. A magnetic element generates a magnetic field whose field distribution is influenced by the disk arrangement. In a magnetic field sensor unit arranged opposite the circumference of the disk arrangement 1, there is a magnetic field sensor element 22 which detects the direction of the magnetic field.
